Getzner Ballast Mats. Depending on the mat type the resilient layer is comprised of one or two layers, each with a density specifically selected to yield the desired overall static and dynamic stiffness. Delkor Rail is a representative of Getzner in Australia.
the efficiency of Getzner ballast mats cannot be applied for ballast mats with different constructions ( compact elastomer mats with profiles or internal cavities). 0 40 80 120 160 200Frequency (Hz) Ballast Mat: Sylodyn DN 335 Sample Dimensions: 200 x 200 x 35 mm ® F' = N/mm22 Load F' = N/mm22F' = N/mm Dyn.
Track Modulus that is "μ". This deflection results in a gap between the rail and sleeper, between sleeper and ballast and annuls in ballast related on the maintenance of the track. The initial modulus at the initial range of 4 tonnes is known as Initial Track Modulus (ITM) and that beyond the range of 4 tonnes load is in fact elastic range...

basalt on the properties of ordinary Portland cement pastes. The rate of hydration was studied from the determination of free lime, combined water and insoluble residue up to 90 days of hydration. The physicomechanical properties such as bulk density, apparent porosity and compressive strength of the hardened cement pastes were determined. .
